I recommend an eyelash curler optimized for Asians.

Please excuse the slight signs of wear since I've used it for a long time haha. It's a Shiseido eyelash curler that I bought when I was a college student and am still using well. The reason Shiseido curlers are famous is that they are designed to fit the curvature of Asian eyes, not Western ones, so they curl your lashes well without pinching your skin. You know how it really hurts when you get pinched sometimes? ㅠㅠ This one doesn't do that, and it really curls my lashes well.
